John and Bon were prompt to answer our questions prior to our booking. Once we confirmed our reservation, Bon sent us detailed information with phone number to get to the Sanctuary House by taxi from the airport. It was easy to follow and very helpful. We were able to check in before noon (our flight landed at 9am) which we appreciated all being jet lagged. The 2BR had guidebooks, maps and brochures, all very handy.
The accommodation was fine, everything functioning well (wifi, ac, fan, cable tv, kettle, tiny kitchen, fridge, washing machine on the rooftop.....). The location was great (near numerous small restaurants, massage places, shops and metro) a very safe and pleasant neighbourhood that we would definitively recommend (even a family with young children - ours were 8 and 10).
The 2BR is ground floor +1 and a bit gloomy, although well lit. Just depends if you are going to be in during the day, in which case the rooftop is very pleasant.
We stayed a week and would stay here again.
